It looks like food prices would go up by about 16%[0], which I would be happy with if I knew that people were getting a fair wage for the labor. If there's a shortage of workers willing to work at such a low wage, then they need to raise wages.
And it's better for something to cost $11.60 and you have a minimum wage job than for that thing to cost $10 and you don't have any job. The difference is astronomical.
